Bougainvillea plant named &#39;Maudi&#39;

ABSTRACT

A new and distinct cultivar of  Bougainvillea  plant named ‘Maudi’, characterized by its outwardly spreading and bushy plant habit; vigorous growth habit; dark green-colored leaves; freely flowering habit; and dark red purple-colored flower bracts.

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Bougainvillea hybrida cultivar Maudi

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Bougainvillea plant, botanically known as Bougainvillea hybrida, and hereinafter referred to by the name ‘Maudi’.

The new Bougainvillea is a naturally-occurring branch mutation of the Bougainvillea hybrida cultivar Zuki, not patented. The new Bougainvillea was discovered and selected by the Inventors from within a population of plants of the cultivar Zuki in a controlled environment in Brisbane, Queensland, Australia in 1995. The selection of this plant was based on its attractive flower coloration and non-variegated leaves.

Asexual reproduction of the new cultivar by cuttings at Brisbane, Queensland, Australia since 1996, has shown that the unique features of this new Bougainvillea are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Maudi have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and/or light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Maudi’. These characteristics in combination distinguish ‘Maudi’ as a new and distinct cultivar:

-   -   1. Outwardly spreading and bushy plant habit.     -   2. Vigorous growth habit.     -   3. Dark green-colored leaves.     -   4. Freely flowering habit.     -   5. Dark red purple-colored flower bracts.

Plants of the new Bougainvillea are most similar to plants of the parent, the cultivar Zuki. In side-by-side comparisons conducted in Moggill, Queensland, Australia, plants of the new Bougainvillea differed primarily from plants of the cultivar Zuki in leaf coloration as plants of the cultivar Zuki had variegated leaves.

Plants of the new Bougainvillea can also be compared to plants of the Bougainvillea cultivar Gloucester Royal, not patented. In side-by-side comparisons conducted in Moggill, Queensland, Australia, plants of the new Bougainvillea differed from plants of the cultivar Gloucester Royal in the following characteristics:

-   -   1. Plants of the new Bougainvillea were more compact than plants         of the cultivar Gloucester Royal.     -   2. Plants of the new Bougainvillea had glossier leaves than         plants of the cultivar Gloucester Royal.     -   3. Plants of the new Bougainvillea flowered more frequently than         plants of the cultivar Gloucester Royal.
